Fastmap works fine with mtdram and NOR flash.
But if your MTD device has less than UBI_FM_MAX_START (64) PEBs
ubi_io_is_bad() will trigger.
The fix is to disable Fastmap if you have not enough PEBs.

I think we enable fastmap only if a MTD device has more than
UBI_FM_MAX_START*2 PEBs.
Any comments?
